HP HP0-Y47 Exam Actual Questions

Refer to the exhibit.


The switch with the ACL shown in the exhibit has IP address 10.1.4/24 on VLAN 4. It is the default router for 10.1.0/24. A client in VLAN 4 broadcast a DHCP discovery request, and the request arrives on this switch.
What happens?

Correct Answer: D 🗳️

For which use case is a basic or standard access control list (ACL) appropriate?

Correct Answer: C 🗳️
Access control lists (ACLs) enable you to permit or deny packets based on source and destination IP address, IP protocol information, or TCP or UDP protocol information.

A network administrator is completing an In-Service Software Upgrade (ISSU) for an Intelligent Resilient Framework (IRF) virtual devices. The device has two members. Each member has one management module. Member1 is currently the master. The administrator has initiated a rollback time for this upgrade.
When should the administrator accept the upgrade?

Correct Answer: A 🗳️
Performing an ISSU for a multi-member IRF fabric
ISSU for a multi-member IRF fabric should be performed as per member in two steps: first upgrade a subordinate member, and then upgrade the master and the other subordinate members.

HOTSPOT -
Match each characteristic to the connect multicast routing protocol. If both protocols exhibit characteristic, you must select both.
Hot Area:

Correct Answer:
* PIM-SM and PIM-DM
Both PIM-SM and PIM-DM use IGMP.
* PIM-SM
PIM Sparse Mode (PIM-SM) explicitly builds unidirectional shared trees rooted at a rendezvous point (RP) per group, and optionally creates shortest-path trees per source.
PM-DM does not use RPs:
PIM-DM differs from PIM-SM in two essential ways:
1) There are no periodic joins transmitted, only explicitly triggered prunes and grafts.
2) There is no Rendezvous Point (RP).
* PIM-DM
Multicast Routing Information Base (MRIB)
This is the multicast topology table, which is typically derived from the unicast routing table, or from routing protocols such as
MBGP that carry multicast-specific topology information. PIM-DM uses the MRIB to make decisions regarding RPF interfaces.
